Simple 3D White Model for SketchUp

Need to convert AutoCAD files into a simple white model for use with SketchUp. I will need to develop my own interior as well as exterior views for use in a lighting design process. I should be able to do a virtual fly-though with the model to be able to navigate and position myself to get good screenshots for my personal rendering process. Therefore, simple and basic furnishings and appliances are a plus, but not required.
